2. Description of Related Art

[0005]

A water gun is designed to shoot or propel water in a tight stream. The traditional water gun operates similar to a spray bottle and is usually a handheld toy shaped like a small handgun. The water gun may be made of hollow plastic that provides a container for the water and a trigger is provided that activates a pump, which squirts the water out of a nozzle.

[0006]

Over time the technology related to water guns has advanced tremendously beyond the traditional trigger pump type of water gun. Other types of water gun include: a syringe/piston type gun where water is expelled from the gun through a syringe or piston like movement; air pressured guns include a water filled reservoir where a pump is used to push air into the water filled reservoir therefore increasing pressure thereon and the air essentially becomes compressed; an air separate pressure firing chamber type water gun works essentially on the same principal as a pressurized reservoir system, however instead of pressurizing the reservoir a separate fixed volume chamber is included on the water gun which water is pumped compressing the air inside; constant air pressure system water guns utilize fiber elastic chambers to power the water gun where the chambers may be symmetrical or spiracle in shape, constant pressure systems have an improved performance over other systems due to lack of firing angle limitations; rubber diaphragm/hydropower water guns utilize elastic rubber bladders to pressurize water; elastic/spring based water guns similar to the air pressure chamber systems utilize a separate air chamber that the water may be pressurized from the elastic nature of a rubber bladder and use metal springs in an order to provide energy behind a stream of water; and peristaltic pumps provide yet another system of water guns that are based upon rollers that pinch a soft piece of tubing and as rollers are rotated they squeeze water through the tubing pushing it in on the length that the rollers remain in contact with the tubing.

[0007]

As the systems of water guns have developed over time various nozzles have been developed to create various spray patterns. The traditional nozzle includes a stream nozzle but other nozzles include a fan type, shower nozzle, blast nozzles, pulsating nozzles and rotating nozzles. Furthermore reservoirs have developed in order to utilize the technology related to water guns. The traditional reservoir is a full body reservoir that is found on the smaller trigger pump type water guns. Larger water guns, which utilize the pressure technique described above usually, include bottle type reservoirs with threaded fuel caps in order to seal the reservoir to create the required pressure associated with the water gun. In addition to reservoir bottles, backpack styled reservoirs may be utilized where the water is essentially strapped to the user's back and allows for increased capacity as opposed to the bottled reservoirs.

[0008]

Some of the more advanced water guns utilize batteries and motors in order to pressurize the reservoirs sufficiently for operational purposes. Many water gun systems require manual pumping to create the required pressure. Although the water gun technology has advanced there remains further advancement and the automated techniques to enhance water gun systems.
